Eh. The US is still very religious. Try running for president as an atheist.

I completely understand how it can be a coping mechanism, but that only works if you believe it. If you stop to think why God would allow millions to die horribly while saving a select few, or why he allows suffering at all, or how he could be omnipotent while we also have free will, or which God is the real God, etc., then believing in it enough to actually draw any peace from that belief is pretty tough.
